Download or read book Molecular Organization of Membranes Where Biology Meets Biophysics written by Marek Cebecauer and published by Frontiers Media SA. This book was released on 2018-02-07 with total page 150 pages. Available in PDF, EPUB and Kindle. Book excerpt: Biological membranes protect cells and organelles from the surrounding environment, but serve also as organising platforms for physiological processes such as cell signalling. The hydrophobic core of membranes is composed of lipids and proteins influencing each other. Local membrane composition and properties define its molecular organisation and, in this way, regulate the function of all associated molecules. Therefore, studying interactions of components, biophysical properties and overall membrane dynamics provides essential information on its function in the context of cell activities. Such knowledge can contribute to biomedical fields such as pharmacology, immunology, neurobiology and many others. The goal of the Research Topic entitled ‘Molecular organisation of membranes: where biology meets biophysics’ was to provide a comprehensive platform for publishing articles, reviews and opinions focused on membrane organisation and the forces behind its heterogeneous and dynamic structure. We collected 11 works which cover topics as diverse as general membrane organisation models, membrane trafficking and signalling regulation, biogenesis of caveolae, protein-lipid interactions and the importance of membrane-associated tetraspanins networks. The prevalent theme was the existence of membrane nanodomains. To this point, new emerging technologies are presented which own the power to bring a novel insight on how membrane nanodomains are formed and maintained and what is their function. We believe that the collection of works in this Research Topic brings forward some important questions which will stimulate further research in this difficult but exciting field.

Download or read book Molecular Biology of Membranes written by H.R. Petty and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 416 pages. Available in PDF, EPUB and Kindle. Book excerpt: This text attempts to introduce the molecular biology of cell membranes to students and professionals of diverse backgrounds. Although several membrane biology books are available, they do not integrate recent knowledge gained using modern molecular tools with more traditional membrane topics. Molecular techniques, such as cDNA cloning and x-ray diffraction, have provided fresh insights into cell membrane structure and function. The great excitement today, which I attempt to convey in this book, is that molecular details are beginning to merge with physiological responses. In other words, we are beginning to understand precisely how membranes work. This textbook is appropriate for upper-level undergraduate or beginning graduate students. Readers should have previous or concurrent coursework in biochemistry; prior studies in elementary physiology would be helpful. I have found that the presentation of topics in this book is appropriate for students of biology, biochemistry, biophysics and physiology, chemistry, and medicine. This book will be useful in courses focusing on membranes and as a supplementary text in biochemistry courses. Professionals will also find this to be a useful resource book for their personal libraries.

Download or read book Physics of Biological Membranes written by Patricia Bassereau and published by Springer. This book was released on 2018-12-30 with total page 623 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book mainly focuses on key aspects of biomembranes that have emerged over the past 15 years. It covers static and dynamic descriptions, as well as modeling for membrane organization and shape at the local and global (at the cell level) scale. It also discusses several new developments in non-equilibrium aspects that have not yet been covered elsewhere. Biological membranes are the seat of interactions between cells and the rest of the world, and internally, they are at the core of complex dynamic reorganizations and chemical reactions. Despite the long tradition of membrane research in biophysics, the physics of cell membranes as well as of biomimetic or synthetic membranes is a rapidly developing field. Though successful books have already been published on this topic over the past decades, none include the most recent advances. Additionally, in this domain, the traditional distinction between biological and physical approaches tends to blur. This book gathers the most recent advances in this area, and will benefit biologists and physicists alike.

This book was released on 2013-06-29 with total page 358 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Advanced Study Institute on "Structure, Biogenesis and Dynamics of Biological Membranes, held in Cargese from June 14-26, 1993, has been dealing with four major topics in membrane biochemistry today: lipid dynamics and lipid-protein interactions, protein translocation and insertion, intracellular traffic aud protein structure and folding. The lecturers discussed these topics starting from several disciplines, including biochemistry, cell biology, genetics, and biophysics. This wayan interdisciplinary and very inte~sting view on biological membrane systems was obtained. At first an extensive overview of -mainly biophysical -techniques which can be used to study dynamic processes in membranes was presented. Sophisticated approaches such as ESR and NMR have been applied succesfully to unravel details of specific lipid-protein interactions. x ray analysis provides detailed structural information of several proteins and the possible implications for protein functions. Information obtained this way is complemented by studies on mechanisms and kinetics of protein folding. The latter information is indispensable when discussing protein translocation and insertion: proces:;es in which folding and unfolding play essential roles. Extensive insight was offered in the complicated machinery of phospholipid biosynthesis. In particular, the application of sophisticated genetic techniques has allowed a better understanding of the mechanisms regulating the synthetic machinery and detailed studies on a variety of mutants, lacking one or more of the essential enzymes, have resulted in the beginning of a bL!:

Download or read book Membrane Organization and Dynamics written by Amitabha Chattopadhyay and published by Springer. This book was released on 2017-12-06 with total page 387 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume brings together information on membrane organization and dynamics from a variety of spectroscopic, microscopic and simulation approaches, spanning a broad range of time scales. The implication of such dynamic information on membrane function in health and disease is a topic of contemporary interest. The chapters cover various aspects of membrane lipid and protein dynamics, explored using a battery of experimental and theoretical approaches. The synthesis of information and knowledge gained by utilizing multiple approaches will provide the reader with a comprehensive understanding of the underlying membrane dynamics and function, which will help to develop robust dynamic models for the understanding of membrane function in healthy and diseased states. In the last few years, crystal structures of an impressive number of membrane proteins have been reported, thanks to tremendous advances in membrane protein crystallization techniques. Some of these recently solved structures belong to the G protein-coupled receptor (GPCR) family, which are particularly difficult to crystallize due to their intrinsic flexibility. Nonetheless, these static structures do not provide the necessary information to understand the function of membrane proteins in the complex membrane milieu. This volume will address the dynamic nature of membrane proteins within the membrane and will provide the reader with an up-to date overview of the theory and practical approaches that can be used. This volume will be invaluable to researchers working in a wide range of scientific areas, from biochemistry and molecular biology to biophysics and protein science. Students of these fields will also find this volume very useful. This book will also be of great use to those who are interested in the dynamic nature of biological processes.

Download or read book Molecular Specialization and Symmetry in Membrane Function written by Arthur Kaskel Solomon and published by Harvard University Press. This book was released on 1978 with total page 366 pages. Available in PDF, EPUB and Kindle. Book excerpt: Biological membranes have been under intensive investigation for several decades. Despite very great experimental challenges, membranes are at last beginning to reveal their secrets. In this book, leading investigators of membrane structure and function report on progress in three related fields: specialization of membrane regions, asymmetry in transport properties, and differentiation of cell faces in epithelia. "Specialization at the Molecular Level" is the subject of the first section; in it, the authors consider such problems as the biogenesis of membranes, the geometry of protein-lipid relationships, and the physical properties of membrane receptor-sites. In the second section, "Asymmetry in Transport," such topics as the sodium-potassium pump, proton translocation, and anion transport are covered. The last section is entitled "Polar Faces in Epithelia" and deals with the complex properties of ion transport across the complex membrane environment maintained by surfaces such as the renal tubular epithelia.

Available in PDF, EPUB and Kindle. Book excerpt: In the first edition of The Enzymes of Biological Membranes, published in four volumes in 1976, we collected the mass of widely scattered information on membrane-linked enzymes and metabolic processes up to about 1975. This was a period of transition from the romantic phase of membrane biochemistry, preoccupied with conceptual developments and the general properties of membranes, to an era of mounting interest in the specific properties of membrane-linked enzymes analyzed from the viewpoints of modem enzymology. The level of sophistication in various areas of membrane research varied widely; the structures of cytochrome c and cytochrome b5 were known to atomic detail, while the majority of membrane-linked enzymes had not even been isolated. In the intervening eight years our knowledge of membrane-linked enzymes ex panded beyond the wildest expectations. The purpose of the second edition of The Enzymes of Biological Membranes is to record these developments. The first volume describes the physical and chemical techniques used in the analysis of the structure and dynamics of biological membranes. In the second volume the enzymes and met abolic systems that participate in the biosynthesis of cell and membrane components are discussed. The third and fourth volumes review recent developments in active transport, oxidative phosphorylation and photosynthesis.

Available in PDF, EPUB and Kindle. Book excerpt: We are extremely pleased that all of the chapters in this volume provide up-to-date information on a variety of topics of interest to scientists working on membrane biology. As in the past, we have attempted to expedite the transition from submission of the manuscripts to publication in order to make the reviews as timely as possible. Cell biology and molecular biology are increasingly be coming concerned with the study of structural elements in cells and their assem bly. The rules which govern membrane synthesis, assembly and interaction of membrane components with other cellular elements, notably the cytoskeleton, are at the center of research in these fields. We will continue in subsequent volumes of this series to focus on these areas. We would welcome suggestions of topics which would benefit from a review at the present time. We thank all of the contributors for providing these very excellent reviews and for doing so in a timely fashion. Elliot L. Elson William A.
